I did use the 150A unit. I've attached the raw .FDR file, so you're welcome to peruse it and play with it for whatever data you'd like to see.
I have a place nearby with a long, wide, flat street where I normally do speed runs. I'll take this set-up out there and throw the ETree on there for a few speed passes and report back.
Here is another version of my first graph. I just filtered Amps values above 100A in Excel.
